Dr. Lessner's research interests center on the vascular biology and biomechanics of atherosclerosis, with an emphasis on intraplaque angiogenesis (new blood vessel growth) and mechanical failure (plaque rupture). Atherosclerotic plaque rupture is a leading cause of acute cardiovascular events such as heart attack and stroke. Evidence available to date suggests that plaque rupture results from an adverse interaction between biomechanical and biological factors. Research in our lab focuses on understanding both these types of factors and their interplay, in order to develop improved methods to reduce the incidence of plaque rupture and its harmful consequences. In terms of the biology of plaque rupture, we focus in particular on the role of intraplaque angiogenesis, or new blood vessel growth, as a destabilizing factor in plaque growth. We also collaborate with faculty in Mechanical Engineering to develop constitutive models of normal and diseased arterial tissue.
